Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188020, here are decompositions:

3 + 188017 = 188020
47 + 187973 = 188020
89 + 187931 = 188020
113 + 187907 = 188020
137 + 187883 = 188020
149 + 187871 = 188020
197 + 187823 = 188020
227 + 187793 = 188020

Showing the first eight; more decompositions exist.
